PLOW.

Application filed May 20,

My invention relates to improvements in plows and the object of the'invention is the provision of improvedfmeans forefl'ecting the raisingand lowering kof the plow.' f

A preferable embodiment of'my invention is shown in the accompanyingdrawing, wherein like numerals of yreference refer to similar parts inthe several'views.

i In the drawings-- Figure 1 is a plan view of Plow. y' f Figure 2 is aside elevation of the plow in raised position. n I` Figure 3 is asideelevation, but with the plow in lowered position. Figure 4 is asection on Figure 1.

l.the improved the lines 4 4 of Referring to the drawingsthe frame ofthe plow is in the form of a beam structure f p i f drawn, but may alsobe horse drawn and the that comprises the plow `beams `5, 6, and 7spaced apart and connected by braces 8, 9, 10 and 11 bolted or otherwiserigidly secured thereto. A plow body 12, constituting 'a plow unit of awellknown type, is carried n by each of the beams 5, 6 and 7. A crankaxle 13 is Vrocka'bly journaled in bearings y14y and 15, supported bythe beams 5 'and 6 respectively, and extends forwardly and downwardly,and on the outer endy thereof is mounted a furrow wheel 16. A crankaxle17 is rockably journaled in bearings 18 and 19, secured to the beams 5and 7 respectively, and extends forwardly and downwardly terminating inan inwardly extending spindle 20, on which is mounted a landwheelf21.,

The plow at its rear is supported in the following manner:` Mounted onopposite sides of the rear ofthe beam 7 are members 22, between which alever 23 `is pivotally supported intermediate its ends, the lower end ofthe leverv being pivotally connected with the bifurcated end of a sleeve24 Vin which is journaled a spindle 25 preferably integral with a crankaxle 26 on the laterally extending portion 27 of which is mounted a nrear furrow wheel 28. The sleeve r24 is pivotally connected intermediateits4 length to links 29 which are'` pivotedfon oppositey sides of thebeam 7. v y Rigidly seouredto the axle `17 kis an yupstanding arm 30, tothe upper portion of. which is pivotally connecte/d afrod 31 thatextends rearwardly and `is slidably supported in a sleeve 32, the latterbeing pivotally connected to the upper end ofthe lever rearwardly thevarm 30.

23. kAdjustable stops 33' on the'frod31 on opposite sides of the Vsleeve32 limit thev sliding' movement of the rod 31. y f i Rigidly secured to`the* axle 13 is.' an upstanding arm 34, to the upper end of which ispivotally connected a bar35 that extends and is pivotally connecte-dwith ltwill thus be seen that if thefaxle is `rocked back 'and y'forthin its bearingsthe armk 30 will lbe oscillatedand by reason of theconnections 31 and 35, movement will be imparted to ythejleverf23and-the arm 34, which will swing the furrow wheelsand act in'conjunctionwith the rocking Vof the landwheel to bodily raise or lower thefbeams inunison dependent upon 'the direction jinV which the axle 17 is rocked.l, l e

Flows fof this Vtype are usuallyvtractor numeral 36`indicates a tractordrawbar or thef'animal draft device, provided withthe customaryprovision for transversefadjustment of the plow hitch, whichr` in thisinstance comprises bars 37 and 38 thatfare Vpivotally connected withthedraw barv or draftY deviceat theirfforward ends and arepivotallyconnected at theirrear ends with a rtransversely positioned'hitch member 39 carried by the plow in a manner that will be hereinafterdescribed,'-the hitch-member 39 being provided with apluralityof holesAto accommodate the adjustment ofthe draft members 37k and 38ytransversely thereof. ln plows of this cla'ssthe depth 'of-plow-IaoLrNn, ammore. nssrenon rok-DEERE ai COMPANY, on

ing is principally regulated by the verticall adjustment of thelandwheel and the front` furrow wheel relatively .to the-plow beams. i

ln the structure'illustrated, the bearing 14 for the' furrow wheelkcrank 'axle 13v is pivotallysupported atr39a upon a bracket40 securedto the beam` 5'thev bearing 14 having secured toit a lever41, by meansof which" the bearing 14 can be swung about the pivot 39 carryingwith'ity the crank axle 13,",the i bea-ring 15 during'such adjustmentacting as the fulcruni for'the axle"13.` The lever 41 is heldin itsvarious positionsfofjadjustment by a notched rack 42, thelevercarryingthe `usual spring actuated locking dog indicated at 43, which engageswith 'the notches in the rack, the dog'being operatedV by the usual hand4latching.mechanism inf y 'dicated at 44.'

The lever 45 is held in VitsV various positions of adjustment by anotched rack 52, the lever carrying theusual spring actuated lockingdogindicated at 53 which engages with the notches in the rack, the dogbeing operated by the usual yhand latching mechanism indiv' cated at 54.

It will be seenthat the pin49 von the yarm ofv the'lever 45 cooperateswith the slotted Vbar 51 to limit the depth to which the plows willYpenetrate,V since when the plowsy are lowered'to operative positionthepin 49 serves as an adjustable abutmenton the plow frame that is adaptedto take the thrust of a stop on the axle 17, in the form of that portionof the bar 51 at the lower end of the slot 50, and resist swinging oftheland wheel axle in a direction to permit descent of the frame, that isto say toward the frame, beyond the level-established by the positionxofthe pin 49. To level'the plow to thek new depth thus established by thelandwheel, the operator should stroke the lever 41 to' lift thefurrowwheel side of the plow relativ'elyto the furrowwheel 16.

The force utilized to raise the plow from working position to transportposit-ion is the Vdrawing power of the tractor or draft animals actingagainst an abutment engaging with the ground, such as that furnishedV bythe plow bodiesor a locked wheel. lThe forces utilized to return'theplow to work-j ing position are gravity; the suck of the plow bodyseeking-its working depth in response to the bend in the draft line,Vdue to the elevation of they plow; and the `drawing power of thetractorordraft animals acting against an abutmentA engaging with the ground,such as that furnished by the plow bodies as they enter theV ground,such latter force beingv utilized to swing the landwheel and furrowwheelaxles in their bearings and load ithe weight of the wheels mountedthereonupon the beams, such latter force Vacting within the limitsestablished by the relationship yof the stop 49 and the slot 50;

' These forces are brought into play and utilized by the means now to bedescribed'.

' The` beams .5 and 6 at their forward ends are connected bya heavy rodbolt upon which yis 'pivotally mounted a Vrocking a member 56,' thelatter as best seen in Figures 11 'and v2, having a pair of upwardly andrearwardly inclined arms 57, said arms with the member 56 vforming arocking support on whichiis pivotally supported a ycrank draft Y Y uponthe Vbegufn6 isg'provided for lifting the Velement in the form of atransversel member 58 having arms 59, to the free ends of which arms arepivotally secured vertically swinging clevises 60 that connect withandcarry the transverse hitch member 39. To the draft element 58 Visrigidly secured a lever 61, the latter having the usual hand latchoperating means 62 that operates a spring actuated locking dog 63,carried by the lever,

which engages with recesses formed in a lever rack 64 secured to therocking sup-VV port 56. In this manner the rocking ,support and theparts carried by it will, as an entirety, swing around the pivot bolt55;

or if thelever be stroked,the crank draft element 58 will be rotated inits supports 57 and the arms 59 swung relatively to'V the rockingsupport V56.

The normal .relationshipV ,oftheY several pivot points is such that whenthe lever 61 is in one position of adjustment relative to its rack, theIdraft force transmitted through the draft members 37 and 38 and thehitch member 39. will act to swing -the rocking support 56 and `itspartsV in one direction,

and when the lever61 is in the opposite position of-adjustmentron itsrack,` the'draft forces act to swing the rocking supportand its parts inthe yopposite direction. rIhis swinging action of the rocking support istransmitted to thewhe'el system of the plow through the medium of a link65 that at its forwardpend is pivotally connected with an upstandingarm66 carried by the rocking .21 to lock Ythe landwheel from rotatingabout the spindle 20. The dog 68 is weighted so that in certainpositionsitvnormally acts by Y gravity to swing free of the teeth ofthemember 69. The dog 68 Vis also connected with the frame of the plow byaV cable 70 so that a predetermined vmovement of the axle 17 in itsbearings willV positively disen gage the dog 68 from the ratchet member69. 71indicates a locking'mcmber pivotally mountedat 7 2V upon a bracket73 carried by the plow beam 6 and its brace 9. The memvber71 is providedwith arecess 74 which is adapted to engage with theJ end 1of .the arm30, when Ythe plow is lifted, and lock the axle 17 against movement initsbearings.VV A. spring 75 acts to press the locking member 71'downwardly and hold it securely `Ain Vengagement with the memberBO.

A bell crank 76 pivotally mountedat'77 CTI :misses locking member 7ltorelease itffrom engagement with the member 3,0 whenit is desired tolower the plow. lAsbest seen in Figure ll, one arm of the bell cranklever extendsl under theA free endof the lockingmemberbl, the other armof the bell ycrank ,lever being connected by a cable ,78 to thelever 6l,

therefore when the lever 61k is stroked forwardly 4the bell crankf isactuated to pry the locking memberyoutof engagement with thearml. l y

Assuming the plow yto be inthe `position shown inl41 igure 2yandthatitis desired to lower the plow, the operator grasps the lever c6l, unlocks it from the rack 64 and strokes it forwardly to the`position indicated in dotted lines in said figure, lockingfthe leveragain to the rack. Such movement of the lever rocks the crank draftelement 58 in its bear' bodies engage the soil. y"During this'moveflment the support 56 has also rocked to some extent on its pivot 55,owing to the link con-k nection 65 with the'armBO. kWhen the plow bodiesContact with the ground, they act as anabutment against which the draftforce operates and as the line of draft .isbelow the pivot the draft.force acts to rock the support 56 rearwardlyabout its pivot 55. Thisrocking movement ofthe `support 5,6 isr communicated through link: r to`the arm 30 which is stroked rearwardly and acts to rocky the landwheelforwardly and upwardly,|` the furrowwheels beingy simultaneously rockedby reason of connections 3l and 35. c The force of the draft `pullingdirectly against the plow bodiesis therefore utilized to relativelyswing the wheels upwardly and depress thebeams until the lower end ofthey slot V5() engages the stop 49, thereby preventing further movementtoward each other of the frame and land wheel axle member after the plowbodies reach a predetermined depth, consequently the plowspenetrate thesoil and reach their working depth very quickly.

Assuming the plow is in position for opf eration at the greatest,depthcit is designed to penetrate, as indicated in Figure, and

that it is desired vto ylift the plow, the operator, grasps the lever6l, unlocks it fromlthe rack 64, and thrusts the lever rearwardly to theposition indicated in dotted lines, lock-i ing it again to the rack.This stroke of the lever rocks the crank draft element 58 inits bearings'on the rocking supporty 56 and swings the arms59and vthe* hitch member,carried thereby, `into the position indicated in dotted` lines in- Fig.n3, whichvit will be noted is above the pivot ,55.y yThe forceof i thedraft pulling against the plow bodies will now acty to lrock kthey'support 56` forwardly about its pivot k55,7orin` a countercclockwisedirection as viewed in said figure', and by'reason of the linkconnection 65 to the arm 80 the latter will be rocked forwardly, thusacting to lift the plows4r upwardlyrelaf tively tothe krwlieels, thestop 49 moving away yfrom the lower end of the slot 50 as this occurs.`Siinultaneously with thethrusti f' ing of the lever lrearwardly and therock-y ing of thek arms- 59 upwardly to the dott-ed kline position,thearc described by the throw ofthe arms 59 acts totighten the cable 67and swing the ydog 68 into 'engagement with the ktoothk member 69,*sothatthelocked landwheel serves asr an yabutment fory the draftfor'ces topull against to raise the plow after ythe plow bodies have` clearedy thegroundsurface.y t will be noted that in liftingvthere is a relativeforward'movement of the draftydevicesas regards theeframve, andacorresponding relative rearward movement in lowering. v

The draft force in rthis manner raises the plow yuntilthe arm 30 dropsin the ,recess 74- o'f the locking chamberl, simultaneously with whichvthe-cable 7G becomes taut and vswings the dog 68 out of engagement withthe ytooth member 69, whereupon the plow will beheld in elevatedpositionfrelativeto the wheels until thelevenGl is engainattu-y ated torelease the lockingy member 7l from the arm 30 and shift the draftdevice into position for the draft force tocause the yplow to enter thesoil. Y c

If, when the vlever 6lv is strokedL tolift the plowthe dog 68shouldengage the tip' of one of the teeth on the member 69,7the

spring 79 `interposed between the arm 59 and the cable G7 will yieldsutliciently to permit the leverftovbe locked to its rack and will pressthefdogagainst thev toothed member. The spring79l will also yield as thecable swingsthe dog'S out of engageico ment with the toothed member atthedeom- 'y pletion of the lifting movement. y e

rllhe raekl may be provided with va kplurality of notches, for the lever6l, as indiy cated, at 80, to'enable the operator to reguf late ytheworking position orvertical elevation of the arms o9 and the draft hitchmemberr 39 carried thereby, relativejto the y 910W! Y, f
